Abstract

A device obtains a service change associated with a cell in a radio network, and identifies helper cells in the radio network that need new random access channel (RACH) parameters due to the service change. The device also determines a RACH parameters configuration for the helper cells, and configures the helper cells with the determined RACH parameters configuration.
